BOTTLE-MOLDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 624,920, dated May 16, 1899.

Application filed J'anuaryl3, 1899. Serial No. 702.038. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES B. GARwoon,

a citizen of the United States of America, anda resident of the city of Baltimore, in the State of Maryland, have invented certain new and.

Heretofore the glass while in its plastic con dition would be placed on a rigidly-fixed base or bottom plate of the bottle-molding device and the two hinged halves of the mold would be brought together, when the desired formation of bottle would be produced by air-pressure in the usual way. It has been found by practical experience that when the hinged halves would travel toward each other they would invariably press upon and drag with their movement a portion of the molten glass and force it beneath the lower edge of the swinging halves of the mold, and thereby produce, when the bottle became cool, a rough, jagged, or unfinished edge on the exterior edge at the. base thereof, thus causing an expenditure of time and labor to remove the defeet by either grinding or filing, thus adding to the cost of production and maintaining an objectionable feature in the process of man ufacture and in the article itself. These objections are obviated by my invention, which I shall fully describe hereinafter.

My invention consists of an automatic slide, forming a part of the base or bottom plate of a bottle-molding device.

In the drawings, Figure 1 represents a plan view of the mold in a closed position. In this view the automatic slide is shown in dotted lines. Fig. 2 represents a similar view to that of Fig. 1; but in this view the swinging or hinged halves of the mold are swung apart and show how one half forces the slide outward and into position for the reception of the molten glass. Fig. 3 is a vertical section taken through the longitudinal center of the slide forming a portion of the base or bottom plate. In this figure the swinging halves of the mold are nearly closed, demonstrating how one of the halves may be brought to its final position, while the other half may operate upon the slide and carry it into position before the molten glass is operated upon.

Fig. 4 represents an elevational View of the base or bottom plate looking toward the end of the slide. v

Similar letters refer to similar parts throughout the drawings, in which (t represents the base or bottom plate, provided with a boss I), a portion of the latter forming a slide 0, whose parallel edges are beveled and adapted to engage with a corresponding formation of the boss I). The slide 0 is connected with the operating-rod d by means of a screw 6, the latter having sufficient play in the aperture f of the base-plate. The outer end of the operating-rod d is bent upward and slightly inward, so as to readily engage with the exterior wall of the swinging half 9 of the mold when the latter is swung outwardly. The rod 61 slides within the depression 7c of the base-plate, as shown. The boss b'when the slide is in a closed position will form a circumferentially-arranged bevel which is adapted to engage with a correspondingly-shaped formation located at the base of the swinging halves g and h. It will here be obvious that the depression 6 is supposed to represent the formation of the exterior base of the bottle. Consequently itis made within the limit of the slide 0.

Mode of operation: The hinged halves g and h are swung apart. The outer wall of the half 9 in its movement comes in contactwith the upright Zof the rod d, and thereby moves it outwardly and at the same time carries the slide 0 with it, as shown in Fig. 2. The operator places the molten glass upon the slide at the depression 21. The half 72. isbrought into position, and the circumferentially-arranged bevel m, located at the base of the half 9, comes in contact with the bevel end of the slide 0 and carries it into position before the mold begins to operate upon the glass. When the halves are brought into their final position, the blower performs his function in the usual way. It will be obvious to those skilled in the art that this mode or process of manufacture will produce a bottle whose exterior edges at its base will have when cooled a perfectly smooth and finished contour, thus producing a desirable product of manufacture.

Having thus described my invention, what I claim as new, and desire to secure by Letters 5 Patent, is-

1. In combination with a base or bottom plate of a glass-molding device of an autoinatic horizontal slide forming a portion of the boss on said bottom plate as herein set 10 forth.

2. In combination with a glass-molding device of the base-plate, the horizontal depres- CHAS. B. GARWOOD.
